MULTIPLIER MECHANISM FOR SHUTTLE-BOX MOTIONS.

Specification of Letters Patent.

Patented Au 20, 1907.

Application filed August 17, 1906. Serial No. 830,946.

To all whom it may concern:

Be it known that I, LESLIE WRIGHT LUTTON, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Multiplier Mechanism for Shuttle-Box Motions, of which the following is a specification.

My invention relates to looms and more particularly to means for operating the shuttle boxes in what is known as a box loom, the object being to shorten the box operating or multiplying chain and at the same time increase its scope in respect to the number of variations in the groups of picks.

In the accompanying drawings, Figure 1 is a view in elevation of a part of the mechanism to which my present invention relates showing the box controlling chain and the multiplying chain and the parts which immediately cooperate therewith, Fig. 2 is a partial view of the same in longitudinal vertical section, Fig. 3 is a view in end elevation, Fig. 4 is a partial view in elevation of the box controlling chain showing the box controlling lever in section, Fig. 5 is an end view of the same, Fig. 6 is a view in detail in transverse section showing the star wheel which is continuously operated step by step and its operating pawl, Fig. 7 is a similar view showing the star wheel which is operated at varying intervals and its sliding pawl in operative relation thereto, and Fig. 8 is an inverted plan view in detail of the sliding pawl and means for controlling it.

The chain for controlling the movements of the boxes is denoted as a whole by 1 and is mounted in position to operate a lever 2, the free end of which is caused to assume different elevated positions, in the present instance three different positions shown in full and dotted lines, Fig. 5, by means of a roller 3 on the end of one of the link spindles which lifts the lever into the full line position shown in Fig. 5; the short projection 4: on the end of an adjacent link spindle which permits the lever 2 to fall into the lowest dotted line position and the extended end of an adjacent spindle 5 which holds the lever 2 at an intermediate point between its uppermost and lowermost positions.

It is understood that the chain 1 is composed of a series of spindles or bars, as is usual, provided with rows located thereon intermediate of the side bars of the links at different distances from the side bars to operate box controlling levers as is usual, this part of the mechanism being omitted as it forms no part of my present invention.

The lever 2 is connected by a rod 6 with the arm 7 of a vibrating angle lever suitably pivoted to the frame at 8 and held under spring tension by means of a spring 9 connected with the end of an extension 10 on the lever and with a fixed point 11 on the frame. The tension of the spring 9 is such as to hold the arm 7 depressed and hence the lever 2 drawn down to the lowermost position permitted by the lever controlling ends of the box chain spindles. An arm 12 on said lever reaches up and engages a slot 13 in a bearing piece 14 attached to a bar 15 which is mounted to slide in a suitable fixed bearing 16 on the frame and which carries at its opposite end a shifting arm 17 engaged with the hub 18 of a sprocket wheel 19 on which the multiplying chain to be hereinafter particularly described is carried.

The sprocket wheel 19 is keyed to the sleeve 20 of the star wheel 21 so as to rotate with the star wheel 21 but at the same time the sprocket wheel 19 and the parts carried thereby may be slid longitudinally along the sleeve 20 nearer to or further away from the star wheel 21 by means of the shifting arms 17 on the bar l5 hereinabove described. The star wheel 21 is loosely mounted on a shaft 22, the same shaft also forming a support for the sprocket wheel 23 on which the box operating chain 1 is mounted and said sprocket wheel 23 is fixed to rotate together with a sleeve 24 which carries the second star wheel 25. The star wheels 21 and 25 are thus mounted in axial alinement, one of them, the wheel 21, carrying with it the sprocket wheel 19 on which the multiplying chain is mounted and the other, 25, carrying with it the sprocket wheel 23 on which the box operating chain is mounted.

The star wheel 21 is operated step of the pin wheel 26, the latter being fixed to rotate with the shaft 27 continuously driven by a pinion 28 connected with a suitable source of power through an intermediate gear 29. The same shaft 27 has keyed to rotate therewith a pin wheel 30 for operating the star wheel 25 but the pin wheel 30 is permitted a sliding movement along the shaft 27 to throw it into or out of operative relation with respect to the star wheel 25 as may be determined by a shifter 31, the said shifter 31 being provided with a bent arm 32, the free end of which is in position to engage a cam surface 33 on the hub of the pin wheel 26 which surface during each revolution of the pin wheel 26 permits the pin to escape from the cam surface and the pin wheel 30 to be thereby thrown into operative relation with respect to the star wheel 25. The shifter 31 is fixed on a sliding shaft 34 mounted in a suitable bearing fixed to the main frame and this shaft and shifter thereon is operated by means of the arm 35 of an angle lever pivoted at 36 to the main frame and under spring tension by means of a spring 37 connected with a depending extension 38 on the lever and with a point on the frame. Another arm 39 of this angle lever is connected by a rod or link 40 with a vibrating overhanging arm 41, pivoted at 42, to a bracket by step by means 43 on the main frame, the arm 41 being in a position to rest on one or another of the rollers on the spindles of the multiplying chain, as follows :The multiplying chain is denoted as a whole by 44. It consists of a series of spindles having rollers 45, 46, 47, etc., mounted thereon, in differentpositions throughout the width of the chain, the several spindles being connected by side bars, as is usual, in chains of this character. The multiplying chain 44 being mounted on the sprocket wheel 19, may be bodily shifted so as to bring the chain in position to have one or another of the rollers where they will engage the lever 41.

As shown in Fig. 1, the multiplying chain is in position where the roller 47 engages the arm or lever 41 and lifts it. If shifted further to the right, the position would be one in which the roller 46 would engage the arm or lever 41 and if shifted still further to the right it would be in position for the roller 45 to engage the arm or lever 41. Thecam 33 is so placed with relation to the elements of the multiplying chain that the shifter 31 is permitted to escape from the cam at the time an operating element on the multiplying chain comes under the lever 41.

The operation is as followsr-The roller 3 on the box chain, by rocking the angle lever pivoted at S, has through the bar 15 thrown the multiplying chain 44 to the left in position for a roller 47 to engage the arm 41. This will, by lifting 011 the rod 40 as by means of the angle lever pivoted at 36, turn the pin wheel 30 intooperative relation to the star wheel 25 and the latter is given a turn one step which will permit the lever 2 to drop into its lowermost position, shown in Fig. 5, as the short end 4 of the spindle on the box operating chain Will not arrest it and this in turn has rocked the angle lever pivoted at 8 in position to shift the multiplying chain 44 to the extreme right where no roller will again engage the arm 41 until the roller 45 is reached and hence the boxes will not be shifted during the next consecutive steps of the star wheel 21 intermediate the rollers 47 and 45. When the roller 45 is reached, it will again, through the arm 41 and rod 40, rock the angle lever pivoted at 36 throwing the star wheel 25 again into action and it will take one step carrying the lever 2 into position to rest on the extended spindle 5 or the intermediate position shown in Fig. 5. This will rock the angle lever pivoted at 8 far enough to bring a roller in the position of the roller 46 on the multiplying chain in position to engage the arm 41 and this will again serve to operate the star Wheel-25 and hence pass the box operating chain into another position under the lever 2.

It will thus be seen that the intervals between rollers located in different planes on the multiplying chain 44 will determine the time the box operating chain shall rest in any given position and hence the number of picks at any given position and that the multiplying \Vhat I claim is 1. In a loom, the combination with the box controlling chain, of a multiplying chain and means under the con trol of the box controlling chain for bodily shifting the multiplying chain to react upon the box controlling chain.

2. In a loom, the combination with a box controlling chain, a'star wheel for moving the chain step by step, a pin wheel movable into and out of operative relation with respect to the star wheel, a second chain, means for imparting to the second chain a continuous step by step movement, means under the control of the second chain for shifting the pin wheel into and out of operative relation with respect to the first-named star wheelv and means under the control of the box controlling chain for shifting the position of the second chain with respect to the pin wheel operating mechanism.

3. In a loom, the combination with a box controlling chain, a lever in position to be operated by the chain, a multiplying chain, means under the control of the said lever for shifting the multiplying chain bodily, a second lever in position to be operated by the multiplying chain and means connected with the said lever for controlling the movement of the box controlling chain.

In a loom, a box controlling chain having certain of its link spindles extended beyond the side bars of the chain, a lever in position to be actuated by such extensions, a multiplying chain, means connecting the said lever with the multiplying chain for shifting it bodily and means under the control of the multiplying chain for con trolling the operation of the box controlling chain. c

5. In a loom, a shaft, two star wheels mounted on the shaft and having their hubs extended in the form of sleeves, a box controlling chain mounted on one of the sleeves, a multiplying chain mounted on the other of the sleeves, means for imparting to the multiplying chain a continuous step by step movement, means in position to engage the multiplying chain to control the step by step movement of the box controlling chain and means in position to engage the box controlling chain for shifting the position of the multiplying chain.

6. The combination with a box controlling chain, a multiplying chain, star wheels for transmitting motion to the chains and pin wheels for driving the star wheels, of means for rotating the pin wheels and means for sliding one of the pawls into and out of engagement with its star wheel, the other of said pin wheels being provided with a cam engaged with the said means for sliding the pin wheel to determine the action of said pawl sliding means.

7. 111 combination, the chain operating star wheels, their pin wheels, one pin wheel having a cam to determine the movement of the other pin wheel, a rocking lever indirectly engaged with the cam, and a chain operated lever connected with the said rocking lever and limited in its movement by said cam.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this thirteenth day of August, 1906.
